Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention generally relates to wireless
communication devices, and more particularly to a wireless
communication device having an integral laser pointer.
[0003] 2. Prior Art
[0004] Useful electronic tools, such as laser pointers, are housed
in pen-like housings, and are widely used in teaching, meeting and
so on. Although such conventional laser pointers are easily
carried, they are susceptible to being forgotten or lost. While
wireless communication devices, such as cellular phones, have
become virtually indispensable to certain persons. One attempt to
combine the two things is disclosed in U.S. Pat. No. 6,327,484,
issued to Siby V. Mathew (the '484 patent). In the '484 patent, a
laser pointer is integrated with a cellular phone. The combination
of the laser pointer and the cellular phone includes a telephony
circuitry, a laser pointer circuitry, a battery and an antenna with
a vacancy therein. The telephony circuitry and the laser pointer
circuitry are coupled to the battery. The laser pointer is disposed
in the vacancy of the antenna with the substantially coherent beam
of visible light is emitted from an end portion of the antenna. One
of the advantages is that a user may readily carry the laser
pointer without being lost or forgotten. The combination also
eliminates a need for a special recharging device for the batteries
used in conventional laser pointers, since the integral laser
pointer can be provided with power from the cellular phone
battery.
[0005] However, such conventional laser pointers integrated with
mobile phones will suffer from calls or messages whenever they are
coming. Under this circumstance, teaching, meeting or presentation
will be undesirablely disturbed. Though this can be avoid by
customization actions, the custoization actions, but this process
is troublesome, time-consuming, and easily being forgotten.
[0006] Accordingly, there is a need in the art for a laser pointer
integrated with a wireless communication device not suffering from
coming calls or short messages, when the laser pointer is in
use.
SUMMARY OF THE INVENTION
[0007] Accordingly, an object of the present invention is to
provide a wireless communication device with an integral laser
pointer not suffering from incoming calls or short messages.
[0008] To achieve the above mentioned objects, the present
invention provides a wireless communication device having an
integral laser pointer, such as a mobile phone, including a
telephony circuitry, a laser pointer circuitry, a ringing
circuitry, a display circuitry and a battery circuitry, wherein the
telephony circuitry, the laser pointer circuitry, the ringing
circuitry and the display circuitry are couplable together to the
battery. A switch is set connecting the battery circuitry by one
terminal, with the other terminal connecting with either the
ringing circuitry and the display circuitry or the laser pointer
circuitry.
BRIEF DESCRIPTION OF THE DRAWINGS
[0009] FIG. 1 is a schematic view of a circuitry for a mobile phone
having an integral laser pointer; and
[0010] FIG. 2 is a perspective view of the mobile phone having an
integral laser pointer.
DETAILED DESCRIPTION OF THE INVENTION
[0011] Referring to FIG. 2, a mobile phone 200 will be taken here
as an example to disclose details of a wireless communication
device having an integral laser pointer 220 according to a
preferred embodiment of the present invention. The mobile phone 200
includes a housing 210, a telephony circuitry 110, a laser pointer
circuitry 120, and other circuitries as shown in the FIG. 1
received therein, and a user interface with a display 230 and a
keypad 240 thereon. The laser pointer 220 is exposed from a top
wall of the mobile phone 200. The display 230 can be set in a
power-saving mode by pressing a key on the keypad 240 when the
laser pointer 220 is in use.
[0012] The keypad 240 includes a plurality of keys (not labeled),
one of which is used to control a first switch 160 (shown in FIG.
1), and actuate the laser pointer circuitry 120; the key used to
control the operation of the laser pointer circuitry 140 can be
either dedicated to such operation, or can be served as a
multi-function key to control other various functions of the mobile
phone 200 based on a mode of operation with beam of light emitting
from an aperture (not labeled) in the mobile phone 200 and
illuminates a small region of a remote surface.
[0013] Referring now to FIG. 1, the mobile phone circuitry 100
comprises a telephone circuitry 110, a laser pointer circuitry 120,
a ringing circuitry 130, a display circuitry 135, a battery 140,
and a first switch 160 therein.
[0014] The telephone circuitry 110 is provided power by the battery
140. The laser pointer circuitry 120, the ringing circuitry 130 and
the display circuitry 135 are selectively coupled to the battery
140 by the first switch 160. Power conversion circuitry 150 may
also be included if the voltage rating of the battery 140 does not
meet the input voltage rating of the laser pointer circuitry 120.
Those skilled in the art are familiar with the use of power
conversion circuitry to modify source of power to meet the
requirements of specific electronic circuitry; the principles of
the present invention are not limited to a specific power
conversion circuitry, such circuit being selectable by those
skilled in the art to meet the specific requirement of chosen laser
pointer circuitry. Furthermore, the principles of the present
invention are not limited to specific laser pointer circuitry.
[0015] The first switch 160 is controllable as a function of the
ringing mode of operation of the ringing circuitry 130 and a
displaying mode of the display circuitry 135. One terminal of the
first switch 160 is electrically connected with the battery 140,
and the other terminal can be connected with either the ringing
circuitry 130 and the display circuitry 135 or the laser pointer
circuitry 120. Generally the first switch 160 is connected with the
ringing circuitry 130, so the mobile phone 100 can be operated as
an ordinary phone. That is to say, when the mobile phone 100 is set
in a ringing and displaying mode, the display 230 in the FIG. 2
will show some information and an incoming call or message will
surely make the mobile phone 100 ringing. When the first switch 160
is set to connect with the laser pointer circuitry 120, the laser
pointer 220 in the FIG. 2 can operated for teaching, meeting or
taking presentations. During this time the ringing circuitry 130 is
disabled to avoid suffering from incoming calls or messages. Thus
even if the mobile phone 100 is set in the ringing mode, coming
calls or coming messages will not ring which will not bother us by
disturbing meeting we are in.
[0016] A second switch 170 may also be included if the laser
pointer 220 is not necessary be turn on all the time. The second
switch 170 can be set between the battery 140 turned off and the
laser pointer 120, so when the first switch 160 is ruined off,
users can turn the laser pointer 220 on or off through the second
switch 170. Of course, the second switch 170 can also be set
between the first switch 160 and the laser pointer circuitry
120.
[0017] For the widely use of the wireless communication, a laser
pointer integrating in the wireless communication will not easily
be forgotten, and will be easily shared with others just like a
mobile phone. The integration of a laser pointer in a cellular
telephone also eliminates the need for a special recharging device
for the batteries used in conventional laser pointers, since the
integral laser pointer can receive power from the mobile phone
battery. When the laser pointer is enable, the ringing circuitry
will be disabled, and at the same time, the display circuitry will
also be disabled to save power.
[0018] It is believed that the present invention and its advantages
will be understood from the foregoing description and it will be
apparent that various changes may be made thereto without departing
from the spirit and scope of the invention or sacrificing all of
its material advantages, the examples hereinbefore described merely
being preferred or exemplary embodiments of the invention.
